Koi fish are known to be the descendants of common carp. They are very hardy fish and come in several distinct varieties. Each koi has its own unique significance. These are classified according to their color, pattern, and scale type. The value of a fish is based in part on how closely its color and markings match the ideal for its breed. One such popular type of koi is the ogon koi.

There are certain things to consider before making an Ogon Koi pond. All year long, your pond should maintain a temperature of between 74 and 86°F. In the winter, you'll need a heating system to keep it from freezing. In nature, the fish would not require a water flow, but if you want to create a small stream or waterfall for aesthetic appeal, they will be fine. The pH of your pond should be maintained between 6 and 9. You may use crushed limestone in your water can to aid with ph maintenance. Water hardness is also an important factor to consider. Ogon koi prefer soft water but can live in neutral or hard water as well.

Your pond will need a filtration system to keep the water clean and the fish healthy. A good rule of thumb is that you should have one square foot of surface area for every one gallon of water. So, for example, a 100-gallon pond should have at least 100 square feet of surface area. This allows for adequate oxygen exchange.

You will also need to provide your Ogon koi with plenty of hiding places. Rocks, plants, and driftwood are all good options. Ogon koi are not aggressive, but they are timid fish and will appreciate having somewhere to hide if they feel scared or threatened.


Ogon koi are omnivorous and will eat a variety of foods. In the wild, they eat insects, crustaceans, and small fish. In captivity, they can be fed pellets, flakes, live food, and frozen food. It's important to provide them with a varied diet so that they get all the nutrients they need to stay healthy.

As with all koi, Ogon koi should not be fed human food. This includes things like bread, crackers, chips, fruit, vegetables, and meat. Human food is not nutritious for koi and can even be harmful. It's best to stick to commercial koi food that has been specifically formulated for their needs.


It is not difficult to breed Ogon koi, but finding excellent breeding stock can be tough. It may either be produced naturally or artificially induced using hormonal injections, which may cause it to occur naturally. The fish will mature sexually between the ages of 2 and 5 years old, and natural breeding will take place in the spring.

Conditioning the fishes before breeding are essential, and a well-conditioned male and female fish will produce good quality eggs. They should be fed food high in protein, including both natural and commercial foods, up to 3 times a day. You can place a fry mat or netting in your pond to catch the eggs as they are released.

The spawning process begins with the male chasing the female and nipping at her fins. She will then release her eggs, and he will fertilize them. The eggs will sink to the bottom of the pond and attach themselves to plants or other objects. It takes about 4 days for the eggs to hatch, and the fry will be free-swimming after another 7 to 10

Ogon Koi Fry Care

Ogon Koi Fry Care

The fry should be kept in a separate tank from the adults. A 20-gallon tank is a good size for up to 50 fry. The water should be the same temperature as the water they were spawned in, and you should use a sponge filter to avoid sucking them up into the filter intake.

For the first 10 days, you don't have to feed them anything as they will be living off their yolk sacs. After that, you can start feeding them baby brine shrimp, daphnia, or other small live foods. After a few weeks, you can start introducing them to commercial koi food. Be sure to crush the pellets or flakes into a powder so that they can eat it.

As the fry grows, you will need to gradually increase the size of their tank. By the time they are 6 months old, they should be moved to a 75-gallon tank. From there, you can move them to a larger pond or keep them in the 75-gallon tank.


Are Ogon Koi Rare? 

Cream specimens are rare and the most popular choices are bright yellow called Yamabuki Ogon and Platinum color koi called Purachina Ogon. The scales on these varieties of koi are non-reticulated.

What Is Orange Ogon Koi? 

Orange Ogon is solid-color koi with a metallic-orange hue. In Japan, they're known as Benigoi, although they're usually referred to in the American koi industry as Orange Ogon.

Ogon Blue Butterfly Koi?

Even though Japanese koi fish are available in many different vibrant colors, there is no such thing as a blue Ogon Butterfly Koi. However, there are Ogon butterfly koi. The term "Ogon" refers to a type of koi with non-reticulated scales, and the term "Butterfly" refers to a koi with long beautiful fins. Therefore, an Ogon Butterfly Koi would be a koi with non-reticulated scales and long beautiful fins, which do not exist.

When choosing a Yamabuki Ogon, it is important to select one with a deep, rich yellow color that is free of any blemishes or black spots.

These are all important factors to consider when choosing a Yamabuki Ogon.


Ogon koi are ornamental fish and are a beautiful addition to any fish pond. They come in a variety of colors, including yellow, cream, and platinum. These fish are relatively low-maintenance fish, but there are still a few things you need to do to keep them healthy and happy. First, you need to perform regular water changes. A good rule of thumb is to change 10-20% of the water every week. This helps to remove any build-up of toxins and keeps the water fresh.

You also need to vacuum the pond on a regular basis. This helps to remove any debris or build-up of waste that could contaminate the water. It's best to do this once a week, but more frequently if you have a lot of fish or plants in your pond.

Finally, you need to monitor the water quality on a regular basis. You can do this yourself with a test kit, or you can take a sample of water to your local pet store for testing. Test the water for ammonia, nitrites, and nitrates. These are all toxins that can build up in the water and harm your fish.

If you follow these simple guidelines, you should have no problem keeping this amazing pond fish koi healthy and happy. With proper care, they can live for 20 years or more.
